    摘要: A lubricating oil composition may include a base oil (A), an olefin copolymer (B), and a poly(alkyl(meth)acrylate) (C), in which a weight average molecular weight of the olefin copolymer (B) is 10,000 to 80,000, a content of the olefin copolymer (B) is 0.01% to 0.23% by mass based on the total amount of the lubricating oil composition, and a content of the poly(alkyl(meth)acrylate) (C) is 0.02% to 0.40% by mass based on the total amount of the lubricating oil composition.

    摘要: A silicone modified lubricant includes a Group I, II, III, IV or V base oil in combination with a minor amount of a silicone oil. Further, the lubricant includes a dispersant such as a dispersant olefin copolymer which maintains the silicone oil dispersed in the base oil. The silicone oil reduces the surface tension of the lubricant thereby reducing power loss. Preferably the lubricant formation has a surface tension less than 28 mN/m, making it particularly suitable for dip lubrication systems.

    摘要: A process for making base oil, comprising: oligomerizing one or more olefins having a boiling point less than 82° C. in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40° C. of 1100 mm2/s or higher. Also, a process, comprising: oligomerizing the olefins in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40° C. of 300 mm2/s or higher and a low cloud point, wherein a wt % yield of products boiling at 482° C.+ (900° F.+) is at least 65 wt % of a total yield of products from the oligomerizing. Additionally, a process, comprising: oligomerizing the olefins in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40° C. greater than 1100 mm2/s and a low cloud point.
